Beware of efax that may come to your email inbox. This week I receive my first efax spam with a source address of "Fax Message [[email protected]]" which contained a link to www.dropbox.com that contained malware. The link has since been removed.

On efax's website, the indicate that you are receiving fax spam to submit the fax via to online form and they "will attempt to prevent further transmission of junk faxes from the source.[2]
